I relied on AMD Eyefinity on Windows for years, especially for triple-monitor gaming. When I switched to Fedora Linux (Wayland + KDE Plasma), I discovered that:

Eyefinity doesn’t exist on Linux, Wayland doesn’t support a “single large surface”, and multi-monitor fullscreen gaming is nearly impossible.

… but after a lot of testing, debugging, and configuration, I finally reproduced Eyefinity-style triple portrait gaming under Linux using gamescope — including:

• 3360×1920 resolution across 3 portrait monitors
• proper fullscreen behavior
• no window borders
• no screen cut-off
• correct mouse input
• stable framerate (VSync 60)
• Unity Engine games working (Universe Sandbox)

Since this was hard to figure out, here is the full solution.

✅ My System

• Fedora Linux 43
• KDE Plasma 6.5.3 (Wayland)
• AMD Radeon Pro W5700
• 3× Portrait Monitors, combined resolution 3360×1920
• Gamescope (nested compositor)
• Example game: Universe Sandbox (Unity)

✅ Steam Launch Options

In Steam, set:

~/bin/gamescope-wrapper.sh %command%

🛠️ Create the wrapper script

Create:

nano ~/bin/gamescope-wrapper.sh

Paste:

```

!/bin/bash

systemd-run --user --scope --quiet \ gamescope \ --force-grab-cursor \ --mouse-sensitivity=1.05 \ --borderless \ --rt \ -W 3360 -H 1920 \ -w 3360 -h 1920 \ -- "$@" ```

Make it executable:

chmod +x ~/bin/gamescope-wrapper.sh

🧩 Why this solves the problem ✔ Gamescope simulates a “virtual Eyefinity monitor”

Wayland does not allow treating multiple monitors as one. Gamescope can, and creates a virtual 3360×1920 display the game believes is a single monitor.

✔ --borderless

Avoids native fullscreen logic (which restricts to one monitor) → Gives a clean fullscreen-style window without decorations.

✔ --force-grab-cursor

Fixes the major Unity issue: Cursor disappearing or becoming invisible when crossing monitor boundaries.

This makes the mouse stable across all 3 portrait screens.

✔ Realtime scheduling (--rt via systemd-run)

Improves frame pacing and input smoothness.

Optional, but recommended:

sudo setcap cap_sys_nice=eip $(which gamescope)

🖥️ Important KDE Setting (must be disabled for gaming)

KDE Plasma has mouse “edge barriers” enabled by default. This makes the cursor stick when moving between monitors.

Disable it:

Right-click desktop → Display Configuration → Screen Edges

Set:

• Top-left corner: No Action
• Corner Barrier: Off
• Edge Barrier Size: 0 px

This lets the mouse move freely across all three monitors.

🧭 KWin Rule (fixes incorrect starting position)

If the gamescope window appears only on monitor 2+3 instead of all 3:

Add a KWin rule:

• Window class: gamescope
• Position: Force → (0,0)

This ensures the window always anchors to the far-left monitor.

🎮 Final Result

• True triple-monitor gaming on Linux (similar to Eyefinity)
• Working mouse input (no disappearing cursor)
• Stable 3360×1920 rendering
• Clean fullscreen without borders
• Unity games work
• KDE edge behavior fixed
• Realtime scheduling for smoothness

This is probably the closest thing to Eyefinity on Wayland right now — and it actually works surprisingly well.

Good luck replicating my setup — I hope this helps someone out there.

Hey there, I have been struggling to re-install Battle.net onto my Linux system which is running Linux CachyOS. I have updated all the software, tried different software (see below photos of each program) with no success. Is there any fix to any of the programs, whether it be Lutris, Faugus Launcher or Bottles?

I was able to have it installed through Faugus Launcher yesterday, but now it just isn't working. I tried opening it multiple times with no success, then I uninstalled it and (attempted to) reinstall and have been encountering this issue repeatedly.

Faugus Launcher when trying to install Battle.net. Unsure why this is popping up. Does the same with Rockstar Games, EA Games and everything else. I have attempted downloading Faugus Launcher through Flatpak command and the KDE Discover Store.

Lutris gives me this error, despite uninstalling and reinstalling the application.

With Bottles, this happens. There have been the occasional times where I could open the application, but it gets stuck on the Update Agent has gone to sleep.

Hello. I've been using different Linux distros ever since I wanted to switch from Windows. I still struggle to understand the real differences in gaming between distros.

For example, I am currently using Kubuntu. Steam works fine in it, and I can play all games I have. Why would I switch to a more gaming-oriented distro like CachyOS? What would the differences even be?

And To be honest, the only real-world differences between distros are the Desktop Environments, in my experience

Hi guys!

I got bazzite installed on my computer and its working great. The GPU is Nvidia so I cannot use game mode due to some glitches so I have settled on booting to desktop then auto launching steam big picture. Does anyone know a way to have the dock hidden when booting?

Right now steam big picture is launching but the desktop is in like an overview mode until I click on steam.

I am using gnome.

Thanks in advance!

Garry's Mod is one of my top games, it's a ton of fun, and I knew that there were issues with it relating to Linux. I already had it at 64 Chromium, installed GMPatchtool, and also did that thing with the autoexec which gives you more performance.

However, for some reason, if I spawn into a map with a lot of stuff in it, the game tanks in FPS and basically becomes a slideshow. I know that my PC is capable of handling the demanding maps, yet since I got into Linux, once I enter the map, the WHOLE game lags, even if I go to a different map. Sometimes I quit out and the game returns to normal, and most of the time if I try that map again, it runs fine, but then I try another map and it lags again.

Is there a step I missed in making GMOD work good on Linux? Please help!

I have no clue if this is the best sub to ask this maybe but, since almost all searches on "vesktop reddit" turn to this sub and there's no official vesktop subreddit maybe I should try asking here (if there are better subs tho please advise me)

My country has in the past few months approved some stupid law like the OSA in UK, to go full in effect by March, so I decided to grab Mullvad to protect myself and my data from it, but it seems Vesktop simply refuses to work with it.

when starting my system, if Mullvad is on the application doesn't even start, but after disconnecting from Mullvad it goes through, but if I try connect again (and honestly, ahving to disconnect in the first place defeats all the purpose) simply NOTHING works, messages on any chat/server fail to load, can't switch between alts nothing.

I've tried 3 servers so far to see if it was a problem with the servers and seems it isn't.

am I doing something wrong?

Hi Everyone,

So I got home and booted my Desktop PC I’ve been using for the past year running Bazzite and booting into Steam Deck mode and it went straight to Desktop.

I then followed the command to reset it like on the website recommends using the command ujust fix-reset-steam it still refuses to work.

Every time I boot the computer, I enter in desktop mode, steam is signed out and I have to log in again. If I try to go to Game Mode Steam crashes, goes back to desktop and asks me to log in again.

Any ideas what’s going on? Thanks

Can somebody who knows what they're doing please help tell me what the fuck it is that I'm doing wrong here? I'm trying to install WiVRN on Kubuntu but apparently it just doesn't exist according to flathub. I'm a Linus Torvalds noob. Please send help. I'm not sure if I correctly added the flathub repositories when installing flathub or not. They made it very vague on this installation link for flathub https://flathub.org/en/setup/Kubuntu as to what they mean by "Flathub is the best place to get Flatpak apps. To enable it, open Discover, go to Settings and add the Flathub repository". Help is appreciated.

So recently I learned that I don't need to "install wine" since I started running things in Bottles Flatpak, but there are still some old games that refuse to launch. If they don't work in WinXP compatibility mode set in Bottles, should I give up or is there something I'm missing?

Like the image shows, this is all it'll show during the startup of the game. It also happens with MSFS 2020, but not always. With MSFS 2024, it's always. The game itself runs fone though, but I'm just wondering why this part missing.

Thoughts?

I been trying to increase my fan speed for awhile now. Everytime I do a sensors check it wont pick up my fan at all. To my knowlege it is hooked up right and it is running so I do not understand why it is not reading. Kinda just frustrated at the whole thing since I have been trying for days.

For clarity, I am running Garuda Linux. Basic gaming laptop. Ran lm-sensors countless times and same story. Won't let me configure any settings for the fan through pwmconfig. Kinda just shows this.

in ~ as 🧙 took 5s
[🔴] × sudo pwmconfig
# pwmconfig version 3.6.2
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/bin/pwmconfig: There are no pwm-capable sensor modules installed

Not sure if I am just stupid and didnt properly set my fans right when I was cleaning them one day or what. But I am kinda just over smacking my head against the wall.

Not new to linux, but by no means a power user. I've dabbled in Ubuntu over the years but typically just run it as a server for docker, pfsense, pihole, etc. I don't play competitive games that need anti-cheat, and don't use my gaming rig for much else anymore. I figure this is the perfect time to try out some gaming-friendly distros and hopefully bid a hearty "get wrecked" to Win11.

I don't use this for console gaming, so leaning towards CachyOS at this point. Bazzite and the Immutable OS seems cool (children's book?), but I actually would like to make changes to the kernel if necessary. Not sure why I'd need to, so might not be a deal breaker. Here's my hardware and what games I mostly play:

CPU/Mem/Mobo: Intel 10850K, 32GB DDR4, Gigabyte Aorus Z490 Elite

VGA: Asus RTX 4070 OC 12GB

Games: Civ6, Civ7, Anno 1800, Anno Pax Romana, Bannerlord 2, Borderlands (all), Helldivers 2

I connect external 144Hz monitor to my laptop. Initially when I used USB-C connector, it only recognized up to 120Hz. Then I bought HDMI connector and it was working fine on 144Hz. A few months go by and today I connected my external monitor again, and to my surprise HDMI doesn't recognize 144Hz at all and only shows bullshit options like 59Hz, 50Hz etc. Surprisingly USB-C connection is showing me 144Hz now lol.

Affected hardware: AOC C24G1 + Zeskit Certified 2.1 8K HDMI Cable combo. Linux 6.17.9-300.fc43.x86_64

Rubbing salt in the wound, my bluetooth driver has been broken since kernel 6.12.. It's slowly draining my patience....

Currently on Win11 and have ASUS H610M motherboard with i5-11400 and 32 GB RAM. No dedicated GPU just onboard.

Getting fed up with Windows and looking to go Linux (Mint, maybe Ubuntu)

Used to game a bit on an older pc until a few years ago but now feel a call back to a couple of games (Asseto Corsa maybe GTA V) but will need a GPU otherwise the games are very jerky.

Quite like the look of the Intel range and have previously had Nvidia.

Looking at spending up to £150 and have a few models in mind.

Just looking for recommendations on the compatibility of Intel and Nvidia GPUs under Linux.

I recently switched to Linux Mint from windows 10 which ran the game fine. I also checked proton db and the game should be playable, but when I launch it everything works untill I hit continue on the menu and the loading screen will eventually freeze. I have tried fixes like changing the proton version and disabling steam overlay but nothing seems to work.

Installed Fedora 43, now trying to setup Lutris AND FSR4 for use with some older games, for now i'm trying with Control.

Optiscaler works and enables FSR, but only FSR3, fsr4 isn't available (it worked on windows10), how do I fix this?

I'm using the same optiscaler I that I used on Windows yet it doesn't show fsr4, I'm running a 9070 xt

Back in the day you could spend hours in a 32bit chroot tinkering to get a wine build working, or you could download it from POL.

Then you could download it from lutris. Then GE and tkg. Tkg does bleeding edge builds through CI now but is there really no-one building versioned good old-fashioned "Just set your path to the bin folder and run it" wine?
